This invention relates to an aeroplane provided with a lifting device,and the object thereof is to obtain at small cost an aeroplane of simpleconstruction without reducing its speed and having big lifting power andcar-. rying capacity and able to land safely. There are many kinds ofaircraft now in use, but they may be roughly divided into the airshipand the aeroplane. The airship has big carrying capacity, can stopfreely in the air and is safe in landing. However", it is expensive andis diflicult to handle and keep. Especially, as. it utilizes gas, thereis a great danger of unexpected explosion caused by electric shock inthe air and other causes. As regards the aeroplane, it has greater speedand is less expensive than the airship. Moreover, it is easier? tocontrol and is more convenient to handle. However, it has comparativelysmall carrying capacity and, cannot stop in the air, Also, it hard tokeep its body stable and especially there is a great danger indescending and landing. The primary object of thisjinvention is toobtain at small cost a safe. aeroplane' of big carrying capacity withlittle danger of explosion and falling by combining the above merits ofthe airship and the aeroplane and providing a kind of compartment tomake good their defects' so that the lifting powermay be increased bythe influence of air currents upon the upper wall of the compartment.

Referring to the accompanying drawings,

Fig. 1 is an ordinary aeroplane having an air compartment on the upperpart of its body,

Fig. 2, a section of its body,

Fig. 4, a plan of a biplane provided with a pair of air compartments atboth sides of its body,

Fig. 5, a front view of the same,

Fig. 6, a section of a wing embodying this invention,

Fig. 7, a section of an aeroplane of big type embodying this inventionand Fig. 8, a plan of the same. The aeroplane according to the presentinvention is provided on a part of its body (1) 376,322; and in JapanOctober 24, 1928.

with one or more air compartments (2) or wings (3) formed in the shapeof'air bag. These air compartments (2) form a kind of wind tunnel, whichhas a control valve (4) at its inlet or front end and a discharge valve(5) at its outlet or rear end, these valves being controllable suitablyfrom the pilots seat.

The air compartment may be constructed substantially in the same manneras the body of the general airship or aeroplane, so far as its structureand the means of covering it are concerned, but is different in respectof having, as stated above, the control valve at its front end and thedischarge valve at its rear end and enabling them to be controlled fromthe pilots seat. In the interior of the air compartment (2) there areanumber of deflectingboards (6) which curve inwardly and backwardly sothat the air current passing through the body of the machine is directedupward. The upper half of the air compartment is preferably providedwith a number of small perforations (8) in order to assist the upwardthrusting of the air current.

Figs. 1 to 3 show an ordinary aeroplane provided with an air compartment(2) at the upper part of its body (1). During the flight so of theaeroplane an air stream flows into the air compartment through the mouth(7) and passes out through the outlet 10, thus imparting to the machinelifting power as indicated by arrows. in the drawing, and part of theair escapes from the small hole (8) of the compartment and assists inchanging the direction of the air current which passes through the body.

Figs. 4 and 5 show an example of a biplane provided with a pair of aircompartments disposed at opposite sides ofthe body (1), in which eachcompartment may be constructed in the same manner as above described. Bythis means it is possible to increase the carrying capacity of themachine and impart stacompartments may be increased or decrease as thecase may be.

Fig. 6 is an exam le of the invention utilized as the wing o anaeroplane, wherein the wing is=of hollow formation and is provided withan inlet (7') at its front end and an air outlet (10) at its rear endand, if necessary, may be provided with a control valve at the air inletand a discharge valve at the air outlet so as'to regulate the aircurrent.-

Figs. 7 and 8 show an aeroplane of big type having an air compartment52) as its body to which is secured or suspen ed a passenger room andfreight cabin (12). This increases the carrying capacity as well as thestability of the machine.

The known aeroplane flies only by wing resistance and therefore it isdifficult to determine the center of gravity of the'machine. Also, whenthere occurs such accidents as the breaking of a wing, or the enginegetting outof-order, etc., the stability of the machine is disturbed.However, an aeroplane according to this invention is not only easy toalways maintain the stability of its body during its travel, but alsoeven when it encounters an accident, it can escape rapid and fatal fallif the discharge valve is "closed, leaving the control valve open.Further, when a landing place is too narrow or a sudden stop isnecessary owing to some obstacle lying before it, the known aeroplanerelies upon only the action of theelevating planes, but in the presentinvention if the discharge valve is closed, the air compartment controlsthe machine and enables it to land safely and without receiving 4 anyimpact.

I claim: a

An aeroplane provided with air compartments adapted to receive aircurrent at their front ends and discharge it at their rear ends said aircompartments being provided with deflectors for deflecting the passingair current and provided in their top walls .with small perforations toassist the upward thrusting of the air current.

In testimony whereof I have aflixed my signature.
